I wanna try out for American Idol

I've always wanted to try out now it's coming to my town which I never thought would happen. It's the audition before the audition. And you would get a ticket to skip the line. I really want to do it, but I was wondering if I could see if I could get feedback on if I sing good or not. Its late, 2AM so its not perfect. And I don't want to sing it acapella but I don't know anyone that plays the guitar.

So who can I email it to?? Please leave your email.
